In Japan “yasou-cha” (wild leaf tea) has been indispensable to keep healthy life.

Mt. Aso is famous for its largest caldera and rich water source, there are plenty of natural herbs around Mt. Aso.

Among others, we focused on great effect of yomogi and dokudami.

However mixing yomogi fiber in tea had been difficult because it gets sticky when it is packed in tea pack.

After many times of trial and error, finally we could have been succeeded in producing our natural wild grasses in compact tea pack.

We don’t use any agrochemical and chemical fertilizer at all in whole process in the production.

The balance and ratio of each ingredients are supervised by Mr Satoshi Izawa (medical herb researcher, president of Aso Herb Factory) who could reduce a certain amount of medical expenses for
many old patients.
